'str'对象没有属性'get' [英] 'str' object has no attribute 'get'

问题描述

我正在Django中进行Braintree集成.我遵循了本指南:

I'm working on Braintree intergration in Django. I've followed this guide:

但是，出现错误'str'对象没有属性'get'.

Views.py

from django.shortcuts import render, render_to_response
from django.http.response import HttpResponse
import braintree
braintree.Configuration.configure(braintree.Environment.Sandbox,
                              "privatekey here",
                              "merchant key here",
                              "public key here")

def form(request):
    return render_to_response('braintree.html')

def create_transaction(request):
    if request.method == 'POST':
        print request.POST.get("number")       
        result = braintree.Transaction.sale({
         "amount": "1000.00",
         "credit_card": {
        "number": request.POST.get("number"),
        "cvv": request.POST.get("cvv"),
        "expiration_month": request.POST.get("month"),
        "expiration_year": request.POST.get("year")
    },
    "options": {
        "submit_for_settlement": True
    }
})

        if result.is_success:
            return "<h1>Success! Transaction ID: {0}</h1>".format(result.transaction.id)
        else:            
            return "<h1>Error: {0}</h1>".format(result.message)
    else:      
        return HttpResponse('no post')

例外是

Environment:


Request Method: POST
Request URL: http://lcoalhost/create_transaction

推荐答案

您是直接从POST块中的 create_transaction 返回字符串.您需要将它们包装在HttpResponse中.

You're returning strings directly from create_transaction inside the POST block. You need to wrap them in an HttpResponse.
